This study assesses the daylighting quality and visual comfort in the Makurdi Airport terminal (Benue State, Nigeria) through occupant surveys and environmental analysis. Makurdi lies in a hothumid tropical climate with high humidity and diffuse solar radiation (clearness index ≈0.43). A structured questionnaire was administered to 343 users (188 staff, 155 passengers) covering air quality, thermal and lighting comfort, and satisfaction. Results reveal divergent perceptions by age and role: older users (36–55 years) rated daylighting and general lighting poorly (100% of 36–55 year-olds said daylight was insufficient), whereas younger users found daylight adequate. Airport staff overwhelmingly rated the lighting system as ―very effective‖ (42%) or ―adequate‖ (37%), while 46% of passengers deemed it ―ineffective.‖ Glare complaints also differed: 46% of staff reported glare in the security area, whereas 53% of passengers reported glare in restrooms and 47% in waiting lounges. Statistical tables highlight these breakdowns. On average, users expressed moderate satisfaction with lighting and ventilation (no respondents were ―dissatisfied‖). Based on these findings and literature, we recommend design interventions: increase filtered natural light (e.g. clerestories or light pipes as in Nigeria’s office building integrate shading (louvers/overhangs) to reduce glare and upgrade artificial lighting to LED with zoned controls. The study fills a gap in tropical airport design by combining user feedback with climate-specific strategies for daylight and glare management, providing evidence-based recommendations for Makurdi and similar contexts.
